We do have a design document but PMC seems to keep removing the link when I attempt to put it, it's currently unfinished but I try to add on to it whenever I find the time: https://www.airshipcraft.tk/docs/book/
It's a server with custom plugins, the goal is to try and be as accessible as possible in-order to read a wider audience and the plugins are planned to be kept open source (for the most part)
to address your other comment, it's a volunteer job.
I'm not looking for knowledgeable people, just people willing to work with whatever skills they currently have. There are plenty of experienced members already part of the team who are more than willing to teach those willing to learn. I myself am still learning Java day by day but that hasn't stopped me from trying to take on this project lol
progress is going really well, still looking for any and all help we can get! especially java developers, builders, and worldbuilders/lore writers and enthusiasts!
yes we already made some progress on the map and the planning phage is almost completely complete by now and we are starting to actually start coding things
